【摘要】：混流裝配是現(xiàn)今許多制造裝配企業(yè)采用的主要生產裝配方式,它能夠在基本不更改現(xiàn)有的裝配手段、裝配條件與裝配能力等前提下,通過改變裝配物料類型、裝配模具大小、裝配工序增減等方式,在一定時間內、在同一條裝配線上裝配出多種產品特性相似、但型號與數(shù)量均不相同的產品,使企業(yè)能夠滿足消費者的各種個性化需求,快速響應市場的變化,保證市場的占有率。本論文主要以某一電動工具公司混流裝配平衡系統(tǒng)為對象進行相關問題改善研究,其主要內容如下:第一章主要對論文的研究背景、研究意義進行了闡述,同時分析了混流裝配平衡系統(tǒng)中作業(yè)排序與物料配送兩方面的一些國內外研究現(xiàn)狀,最后描述本論文主要的研究內容和組織結構框架。第二章對精益思想與混流裝配系統(tǒng)這兩方面的相關理論與方法進行了描述,其中精益思想中主要涉及均衡化生產與精益物流的概念與改善方法,而混流裝配系統(tǒng)則是作業(yè)排序與物料配送的概念與方法。第三章對B電動工具公司一廠混流裝配系統(tǒng)的現(xiàn)狀進行了了解與分析,先介紹一廠的布局和裝配情況,再從作業(yè)排序與物料配送這兩個方面進行現(xiàn)存問題的描述與分析。第四章針對一廠混流裝配系統(tǒng)中作業(yè)排序方面存在的問題進行改善,先綜合考慮實際客戶訂單與短期市場預測進行生產裝配計劃的制定,再應用最小生產循環(huán)(MPS)原理將裝配計劃進行均勻劃分,確定每次循環(huán)需裝配各型號產品的產量,然后又分別建立目標為生產裝配均衡化和總換型時間最短的兩個數(shù)學模型,綜合考慮建立兩者的總目標函數(shù),以求出MPS中各型號產品的相對最優(yōu)排序。最后以線5混流裝配線上的三個不同型號的電動工具混流裝配計劃為例,進行其最優(yōu)作業(yè)排序結果的計算。第五章針對一廠混流裝配系統(tǒng)中物料配送方面存在的問題進行改善,從物料分類管理、物料配送方式、物料配送路徑、物料配送時間等方面進行設置與規(guī)范化管理,將改善后的效果與原先狀況進行比較。第六章對全文進行了總結,描述了本論文的主要研究工作與不足之處,對后續(xù)的研究進行展望。
[Abstract]:Assembly is the main production assembly used today many manufacturing and assembly enterprises, it can not change the basic assembly method, existing assembly condition and assembly capacity under the premise, by changing the material type, the mold assembly assembly size, assembly process or other way, in a certain period of time, on the same assembly line out a variety of products, but the type and quantity characteristics of similar products are not the same, so that enterprises can meet the individual needs of consumers, rapid response to market changes, to ensure the market share. This thesis is mainly based on the mixed model assembly balance system a power tool company as research object to improve the related problems, the main contents are as follows: the first chapter is mainly on the research background and significance are described, and analyzed the domestic and foreign research status quo of the two aspects of order and material distribution in the balance system of row assembly operations finally, the thesis describes the main research content and structure frame. The second chapter describes the related theory of the two aspects of lean and assembly system and method, the concept of lean thinking mainly involves the balance of production and lean logistics and improving method, and assembly system is the concept and method of scheduling and material delivery. In the third chapter, we understand and analyze the current situation of the mixed assembly system of B electric tools company. First we introduce the layout and assembly of a factory, then describe and analyze the existing problems from two aspects: job sequencing and material distribution. In the fourth chapter, a system of mixed model assembly plant scheduling problems to improve the first comprehensive prediction made in assembly planning considering the actual customer orders and the short-term market, using the minimum production cycle (MPS) principle of partitioning the assembly plan, determine each cycle required assembly products of various types of production, then are established respectively for the production assembly equalization and two mathematical models of the total exchange time of the shortest, considering the establishment of a general objective function of the two, in order to find out the relative optimal ordering of the product in MPS. At last, three different models of electric tools mixed flow assembly plan of the line 5 mixed flow assembly line are taken as an example to calculate the optimal operation sequencing results. The fifth chapter according to the existing material assembly system in factory distribution problems to improve the setting and standardized management from the material classification management, material delivery, material delivery path, material delivery time etc., will improve the result and the original condition for comparison. The sixth chapter summarizes the full text, describes the main research work and shortcomings of this paper, and looks forward to the follow-up research.
